A significant share of the broader ‘singularitarian’ community believes that they have a chance to live for hundreds of years, if they can survive until the arrival of an AI singularity, whole brain emulation, or just the point at which medical technology is advancing fast enough to keep extending our health-span by at least a year each year (meaning we hit ‘escape velocity‘ and can live indefinitely). Some are sufficiently hopeful about this to have invested in cryonics plans, hoping to be revived in the future, including Robin Hanson. Many others plan to do this, or think they should. (For what it’s worth, I am not yet convinced cryonics is worth the money – for reasons I am writing up – but I do think it warrants serious consideration.)

But there are much more mundane ways of increasing the chance of making it to this glorious future: exercise regularly, eat a nutritious diet low in refined carbohydrates, don’t smoke or hang around those who do, drink in moderation, avoid some illegal drugs, develop strong social supports to lower suicide and other mental health threats, have a secure high-status job, don’t live in an urban area, don’t ride a motorbike, get married (probably), and so on. While the futurist community isn’t full of seriously unhealthy or reckless people, nor does it seem much better in these regards than non-futurists with the same education and social class. A minority enjoy nutritional number crunching, but I haven’t observed diets being much better overall. None of the other behaviours are noticeably better.

I am fairly confident that the lowest hanging fruit would be raising fitness levels, which may even be lower among us than the general population. In addition to the immediate benefits regular and strenuous exercise has on confidence, happiness and productivity, it makes you live quite a bit longer. One study suggests that just 15 minutes of moderate exercise per day adds three years to your life expectancy (HT XKCD).

Now, maybe you are skeptical that those few years will allow you to live long enough to reach the end of involuntary death. Probably they won’t, but the whole life extension approach is to bank on a low chance of a giant payoff (living for hundreds or thousands of years). Furthermore, as the Singularity Institute has compellingly argued, we should not think we can confidently predict when AGI will be invented, if at all. The same is true to a lesser extent of progress towards whole brain emulation, or ending ageing. Furthermore, cryonics preservation procedures, and the selection of organisations that offer cryonics are gradually improving. Extending your life by five to ten years by doing all the ordinary things right could really make the difference; at least anyone considering gambling on cryonics should surely also find regular jogging worth their time.

I have even heard smart people claim that there is no need to worry about staying healthy because new technology will cure any diseases you get by the time you get them. But uncertainty about how soon such technologies will appear, combined with the high potential reward of living a little longer, would suggest exactly the opposite.

If I had to provide a cynical explanation for this apparently conflicting behaviour, I would suggest people are signing up for cryonics, or engaging in nutritional geekery, to signal their rationality and membership of a particular social clique. Going to the gym, even if it is a better bet for extending your life, doesn’t currently have the same effect. If you fear you’re stuck in that or some similar trap, consider using Stickk or Beeminder to make sure you do the rational thing.
